Description

  The present invention relates to a method for treating hair.

  Conventionally, what is called a hair rinse or a hair treatment has been applied for the purpose of improving the flexibility and goodness of the comb. In general hair rinses and hair treatments, a cationic surfactant is used as a main ingredient as a component that enhances flexibility and combing quality. These general hair rinses and hair treatments also contain fats and oils, higher alcohols, silicone oils, polyhydric alcohols, etc. to protect the hair surface, impart luster, and further improve combability. Has been.

  However, recently, with the spread of permanent waves and hair dies, damage to the hair itself has increased, and general hair rinses and hair treatments are hardly expected to improve various properties of the hair. Under such circumstances, a technique for treating hair using methyl hydrogen polysiloxane (methyl hydrogen polysiloxane) has been proposed (Patent Document 1).

  This methyl hydrogen polysiloxane has the effect of imparting hydrophobicity and water resistance to a powder having hydrophilicity by hydrophobizing its surface. For example, such a powder can be applied to cosmetics. When blended, it is used to prevent aggregation of the powders. In the technique of Patent Document 1, focusing on the fact that methylhydrogenpolysiloxane can be combined with OH groups and SH groups in hair and also with hair treatments, this is used as a pretreatment agent before using hair treatments. Methyl hydrogen polysiloxane is contained to improve the flexibility and fingering property of the hair.

  It is also known to mix amino-modified silicone, which is a component capable of imparting softness and moist feeling to dried hair, into hair rinses and hair treatments. For example, Patent Document 2 discloses a hair treatment composition comprising a combination of amino-modified silicone and low-viscosity silicone in a certain ratio, and further containing a cationic surfactant, a betaine-type amphoteric surfactant, and a higher alcohol. ing.

  Furthermore, as a technique for improving the sustainability of the hair modification effect by hair rinsing, hair treatment, etc., a first agent containing an amino-modified silicone having a specific structure and a non-aqueous system containing a methyl hydrogen polysiloxane having a specific structure A hair treatment method has been proposed in which a second agent and a third agent containing an amino-modified silicone having a specific structure are applied (Patent Document 3).

  Conventional hair rinses and hair treatments usually have to be treated each time the hair is washed because the modified effect is lost by washing (washing) the treated hair. However, recent hair rinses and hair treatments are required to have such characteristics that the effect of modifying the hair is maintained even if the hair is repeatedly washed to some extent. In the techniques of Patent Documents 1 and 2, sufficient studies have not been made on the durability of the hair modification effect when the hair is repeatedly washed.

  Moreover, although the technique of the said patent document 3 makes the subject of the sustainability of the modification | reformation effect of hair, methyl hydrogen polysiloxane is used. The use of this methyl hydrogen polysiloxane has the following problems.

  Since methyl hydrogen polysiloxane reacts with water to produce hydrogen gas, hair treatment agents that contain methyl hydrogen polysiloxane generate hydrogen gas over time, which can improve stability and safety. There is a problem in terms.

  Also, methyl hydrogen polysiloxane is used in non-aqueous systems using a lower alcohol such as ethanol or isopropanol or an ester oil such as isononanoyl isononate as a solvent for reasons such as solubility and permeability to hair. However, when a lower alcohol such as ethanol is used as a solvent and a solution having a high content of the lower alcohol is used, there are disadvantages that the scalp is strongly stimulated and the hair dye is liable to fade. Moreover, when oils, such as ester type oil agent, are high content, it will give the hair the excessive oily feeling which was sticky, and the effect of methyl hydrogen polysiloxane cannot fully be drawn out.

  The present invention has been made in view of the above circumstances, and in particular, the durability of the hair modification effect such as improving the flexibility (softness) of the hair and improving the uniformity of the hair as it is fingered is good. And it aims at providing the processing method of hair excellent also in safety | security.

  The method for treating hair of the present invention that has achieved the above-mentioned object includes a step (A) of applying to the hair a hair internal repair agent containing at least water and a component having an action of repairing the inside of the hair, A non-aqueous pretreatment agent that is implemented after the above step (A) and contains at least methyl hydrogen polysiloxane, polyoxyethylene polyoxypropylene alkyl ether represented by the following formula (1), and an acid: The step (B) for applying to the hair, and the step (C) for applying a hair modifying agent, which is carried out after the step (B) and containing at least an amino-modified silicone, to the hair. It is characterized by.

[In the above formula (1), R represents an alkyl or alkenyl group having 1 to 24 carbon atoms in which one or more hydrogen atoms may be substituted with a substituent, 1 ≦ m ≦ 20, 1 ≦ n ≦. 8. ]

  In the treatment method of the present invention, through the three steps of step (A), step (B) and step (C), the inside of the hair is repaired and a film having a hair modifying effect is applied to the hair surface. Since the hair is formed and modified from both the inside and the surface of the hair, the effect is good. Moreover, since the surface of the hair whose inside has been repaired is covered with the above-described film, the sustainability of the effect is good. Furthermore, in the present invention, the pretreatment agent containing methylhydrogenpolysiloxane suppresses the reaction of methylhydrogenpolysiloxane with water while preserving the pretreatment agent while minimizing irritation to the human body. In addition, the treatment method of the present invention is excellent in safety because it is configured to sufficiently extract the action of methyl hydrogen polysiloxane.

  As described above, a film having a modifying effect is formed on the surface of the hair to be treated by passing from the process (A) to the process (C). It is derived from the amino-modified silicone compounded in the quality agent [Further, this film formation involves methylhydrogenpolysiloxane compounded in the pretreatment agent used in step (B)]. Therefore, if a part of the film is damaged in normal life and the deterioration of the effect occurs, the film is damaged by applying a film repair agent containing at least amino-modified silicone. It is preferable to repair the location. That is, in the treatment method of the present invention, after the step (C), a film repair agent containing at least an amino-modified silicone is applied to break the film derived from the amino-modified silicone formed on the hair surface. It is preferable to further include a step (D) of repairing the portion. By the step (D), it is possible to suppress the deterioration of the hair reforming effect by the film and improve the sustainability of the effect.

The amino-modified silicone used for the hair internal repair agent includes aminoethylaminopropylsiloxane / dimethylsiloxane copolymer [for example, one represented by the following formula (2)], and aminoethylaminopropylmethylpolysiloxane / dimethylpolysiloxane. Examples thereof include siloxane copolymers [for example, those represented by the following formula (3)]. Such amino-modified silicone forms a film having a strong resistance to washing on the hair surface, and can impart a durable combing, soft feeling and gloss. Moreover, the effect that the damage of the hair by using dryer is reduced can also be acquired.

[In the above formula (2), A represents — (CH ₂ ) ₃ NH (CH ₂ ) ₂ NH ₂ , and o> 1, p> 1, and o + p> 10. In the above formula (3), A is the same as A in the above formula (2), q> 1, r> 1, and q + r> 10. ]

  Examples of commercially available aminoethylaminopropylsiloxane / dimethylsiloxane copolymers include “SM8704C” (manufactured by Toray Dow Corning Silicone) and “XF42-C0330” (manufactured by GE Toshiba Silicone). Examples of commercially available aminopropylmethylpolysiloxane / dimethylpolysiloxane copolymers include “SF8451C” and “SF8452C” (manufactured by Toray Dow Corning Silicone). These amino-modified silicones may be used alone or in combination of different types.

  Moreover, as said polyoxyalkylene benzyl ether, 2 mol of ethylene oxide is added by the average number of moles with respect to 1 mol of benzyl alcohol, and / or with the average number of moles with respect to 1 mol of benzyl alcohol, What added 2 mol of ethylene oxide and 1 mol of propylene oxide is preferable.

  By blending polyoxyalkylene benzyl ether with an amino-modified silicone in the hair internal repair agent, the amino-modified silicone adheres from the tip of the hair to the middle stage of the hair, and in particular prevents sticking to the root of the hair. Generation of a feeling and uneven gloss can be suppressed. As polyoxyalkylene benzyl ether, for example, 1 mole of benzyl alcohol is added with 2 moles of ethylene oxide in an average mole number [hereinafter referred to as polyoxyethylene (2E.O.) benzyl ether. Here, (2E.O.) is the average added mole number of ethylene oxide. ] Or an average number of moles of 2 moles of ethylene oxide and 1 mole of propylene oxide added per mole of benzyl alcohol [hereinafter referred to as polyoxyethylene (2E.O.) polyoxypropylene (1PO] .)

It is preferable that an anionic polymer such as amide is blended and that the hair internal repair agent is adjusted to pH 5 or less. When the pH of the hair internal repairing agent in which the anionic polymer is blended is adjusted to 5 or less, the amount of the anionic polymer adsorbed on the hair end portion where hair is easily damaged increases. The anionic polymer blended in the hair internal repair agent is adsorbed on the hair surface, but cationic compounds such as cationized polymers and cationic surfactants are used in the hair modifier used in the step (C) described later. When blended, the adhesion of the cationic compound to the hair surface is improved by the interaction between the anionic polymer and the cationic compound, and the effect of imparting a soft texture to the hair is more effectively exhibited. In this case, the pH of the hair internal repair agent is more preferably 4 or less, further preferably 3 or less, and preferably 2 or more.

  If the hair internal repair agent contains only the necessary components and has the above pH, there is no need to adjust it separately, but if it is necessary to adjust the pH of the hair internal repair agent, pH adjustment What is necessary is just to mix | blend an agent with a hair internal repair agent.

  The hair repair agent can be in the form of, for example, a cream, a lotion, or a gel, and water is the main dispersion medium. Note that some of the various components described above may be dissolved in water. Further, all of the dispersion medium may be water, and may contain an organic solvent such as a lower alcohol (ethanol, isopropanol, etc.). However, if the amount of the organic solvent in the dispersion medium is increased, the scalp and the like may be stimulated. Therefore, the content of the organic solvent in the dispersion medium is preferably, for example, 5% by mass or less.

  In addition, the hair internal repair agent can use what differs in a component composition according to the property of the hair to process. For example, in the case of thin hair or hair of normal thickness and relatively undamaged, for example, water as a dispersion medium, the above vegetable-derived protein derivative: 0.01 to 1 mass %, The above ceramides and / or cholesterol: 0.001 to 0.1% by mass, the above basic amino acids: 0.01 to 1% by mass, the above phospholipid polymer: 0.01 to 1% by mass, The above-mentioned cationic surfactant: 0.5 to 5% by mass, the above higher alcohols: 1 to 10% by mass, the above amino-modified silicone: 0.1 to 3% by mass, etc. It is preferable to use a repair agent.

Immediately after the application of the hair internal repair agent, the process may proceed to the next step [Step (B)]. For example, after about 5 to 10 minutes, the process may proceed to the next step [Step (B)].

  Next, a pretreatment agent is applied to the surface of the hair after applying the hair internal repair agent [step (B)]. The methyl hydrogen polysiloxane blended in the pretreatment agent used in this step (B) can form a chemical bond with the amino-modified silicone blended in the hair modifier used in the next step (C). The film formed on the hair surface by the amino-modified silicone has the effect of enhancing the adhesion to the hair surface. That is, this process (B) is a process for forming the foundation | substrate for the membrane | film | coat formed by process (C).

  The pretreatment agent used in step (B) contains at least methyl hydrogen polysiloxane, polyoxyethylene polyoxypropylene alkyl ether represented by the above formula (1), and an acid.

  As described above, methylhydrogenpolysiloxane is a component that improves the adhesion of the film formed by the amino-modified silicone used in step (C) to the hair surface, but has further excellent flexibility and combability. It also has the effect of imparting to hair. The methyl hydrogen polysiloxane is one obtained by substituting a part of the methyl group of methyl polysiloxane with hydrogen. Examples of commercially available products include “SH1107C” (manufactured by Toray Dow Corning Silicone), “ KF-99 "(manufactured by Shin-Etsu Chemical Co., Ltd.).

  The polyoxyethylene polyoxypropylene alkyl ether and acid blended in the pretreatment agent are components for improving the safety and stability (stability with time) of the pretreatment agent. Generation of hydrogen gas due to the reaction between water and water is suppressed. In addition, polyoxyethylene polyoxypropylene alkyl ether has the function of further improving the hair flexibility improvement effect and the combing lightness improvement effect of methyl hydrogen polysiloxane by coexisting with methyl hydrogen polysiloxane. Also have.

And the compounding quantity of an acid is 0.005 mass% or more, More preferably, it is 0.01 mass% or more, It is desirable to set it as 1 mass% or less, More preferably, it is 0.1 mass%. Further, the entire pretreatment agent may be adjusted to 100% by mass including the surfactants, oils, fragrances and the like exemplified above. As described above, when a high content of an organic solvent such as a lower alcohol is used as a solvent for methyl hydrogen polysiloxane, there is a concern of irritation to the scalp, and there is a high content of oils such as ester oils. When used, it gives a sticky feeling to the hair. However, in the pretreatment agent, the polyoxyethylene polyoxypropylene alkyl ether represented by the above formula (1) is used, for example, in the above blending amount, thereby reducing the amount of use of an organic solvent, an ester oil, or the like, or Since it can be eliminated, it can be made low in irritation, excellent in safety and without giving a sticky feeling.

  The amount of the pretreatment agent applied to the hair is preferably, for example, 2 to 10 ml with respect to the length of hair on the shoulder. In addition, it is preferable to apply | coat a pretreatment agent to the position of the middle vicinity of the length direction centering on the hair tip vicinity. When the film obtained by the step (C) after this step (B) is formed near the root of the hair, it may give a sticky feeling or non-uniform luster to the hair. Therefore, for the pretreatment agent used to increase the adhesion of the film to the hair, the formation of the film in the vicinity of the hair root can be suppressed by avoiding the application to the hair root. It is.

  After application of the pretreatment agent, it is preferable that the pretreatment agent is sufficiently blended into the hair by, for example, penetration and combing. Thereafter, the hair is washed with water. Moreover, you may wash with water after wash | cleaning with a shampoo. This water washing enhances the reaction activity of methyl hydrogen polysiloxane adhering to the hair surface and promotes the formation of chemical bonds with the amino-modified silicone compounded in the hair modifier applied in step (C). can do.

  Next, a hair modifier is applied to the hair after applying the pretreatment agent and washing with water [step (C)]. By this step (C), a film derived from amino-modified silicone is formed on the hair surface. This film can impart good combability, flexibility, luster, and the like to the hair, and also improve the resistance of the hair to the heat of the dryer. Moreover, the said membrane | film | coat has strong resistance with respect to washing | cleaning by the coupling | bonding of amino-modified silicone and the methyl hydrogen polysiloxane in the pretreatment agent apply | coated to the hair at the process (B). Therefore, the sustainability of the effect by the film is also good.

Further, all of the dispersion medium may be water, and may contain an organic solvent such as a lower alcohol (ethanol, isopropanol, etc.). However, if the amount of the organic solvent in the dispersion medium is increased, the scalp and the like may be stimulated. Therefore, the content of the organic solvent in the dispersion medium is preferably, for example, 5% by mass or less.

  As the hair modifier, those having different component compositions can be used depending on the properties of the hair to be treated. For example, in the case of thin hair that is not relatively damaged, for example, the above amino-modified silicone: 0.1 to 1% by mass, water as a dispersion medium, the above cyclic polymer and / or spherical shape Polymer: 0.5-5% by mass, ester oil such as isodecyl neopentanoate: 1-10% by mass, cationic surfactant: 0.5-5% by mass, and the above higher alcohols: It is preferable to use a hair modifying agent containing 1 to 10% by mass or the like. In addition to these components, for example, the various components exemplified above may be blended with the hair modifier.

  When the hair has a normal thickness and is not relatively damaged, for example, water is used as a dispersion medium, and the amino-modified silicone is 0.1 to 3% by mass, and the cyclic is used. Polymer and / or spherical polymer: 0.5 to 5% by mass, the above lanolin fatty acid ester: 0.1 to 1% by mass, ester oil such as isodecyl neopentanoate as described above: 1 to 5% by mass, the above cationic It is preferable to use a hair modifier comprising a surfactant: 0.5 to 5% by mass and the above higher alcohols: 1 to 10% by mass. In addition to these components, for example, the various components exemplified above may be blended with the hair modifier.

  Furthermore, for relatively hard hair, hair with a habit (so-called comb hair), wave hair treated with a permanent wave agent and the like, for example, the above amino-modified silicone: 1 to 5 masses using water as a dispersion medium %, The above wax esters: 1 to 5% by mass, the above cationized polymer: 0.01 to 1% by mass, the above cationic surfactant: 0.5 to 5% by mass, and the above higher alcohols It is preferable to use a hair modifier comprising 1 to 10% by mass or the like. In addition to these components, for example, the various components exemplified above may be blended with the hair modifier.

  In particular, for hair treated with a hair internal repair agent (particularly one having a pH of 5 or less) in which the above anionic polymer is blended, the above cationized polymer or the above cationic surfactant is used. By using a hair modifier that contains a cationic compound such as the above, the adhesion of the cationic compound to the hair surface is improved by the interaction between the anionic polymer and the cationic compound, and the hair has a soft texture. The imparting action is more effectively exhibited.

  The cationic surfactant corresponding to the cationic compound in the hair modifying agent is not particularly limited, but alkyltrimethylammonium chloride such as lauryltrimethylammonium chloride and stearyltrimethylammonium chloride, and distearyldimethylammonium chloride. Further, quaternary ammonium salts such as cetyltrimethylammonium bromide and stearyltrimethylammonium bromide are preferable. Among the above quaternary ammonium salts, those having anion species of bromide, that is, cetyltrimethylammonium bromide and stearyltrimethylammonium bromide are more preferable in that the adsorptivity to hair is particularly good. Furthermore, cetyltrimethylammonium bromide is particularly preferred in that it has a more excellent effect of imparting softness to hair.

  The amount of the hair modifying agent applied to the hair is preferably 10 to 20 g, for example, with respect to the length of hair on the shoulder. In addition, it is preferable to apply the hair modifying agent to a position near the middle of the length method with the vicinity of the tip of the hair as the center. This is because, as described above, when a film derived from amino-modified silicone is formed in the vicinity of the root of the hair, it may give the hair a sticky feeling or uneven gloss.

  After application of the hair modifying agent, it is preferable that the hair modifying agent is sufficiently blended to fully adjust the hair modifying agent to the hair. Thereafter, the hair is washed with water and dried.

  The hair treated in this way has water and various components infiltrated into the inside thereof to be in a good internal state, and a film derived from amino-modified silicone is formed on the surface thereof. Improved texture. Moreover, the said film | membrane formed in the hair surface is excellent in the tolerance with respect to washing | cleaning, and can suppress discharge | release to the exterior of the water | moisture content inside hair. Therefore, in the hair after the treatment by the treatment method of the present invention, the effect of the treatment is sustained for a relatively long time.

  In addition, also in the hair after the said treatment, the film | membrane on the hair surface is damaged gradually by continuing normal life, The effect is lost. When the degree of deterioration of the effect by the treatment is large, the hair may be treated again by the treatment method of the present invention. For example, the film on the hair surface is locally damaged, and the effect of the treatment is effective. Under the condition where the degree of deterioration is small, the film repair agent described later is applied to the hair [Step (D)] to repair the film, and the effect of the treatment can be further maintained.

  As the film repairing agent used in the step (D), one containing an amino-modified silicone which is a raw material for the film on the hair surface is preferable. As the amino-modified silicone, the same ones as exemplified as the amino-modified silicone according to the hair modifying agent are suitable.

  In addition to the above-mentioned amino-modified silicone, the film repair agent includes a component having an action of imparting a slipperiness to the hair surface (such as a cyclic polymer such as decamethylcyclopentasiloxane), and water content inside the hair covering the hair surface. It is preferable that a component having an action of suppressing release (wax esters such as jojoba oil) is blended.

  In addition to the amino-modified silicone and the various components described above, various known additives used in hair rinses and hair treatments can be blended in the film repair agent. Examples of such additives include silicones (excluding those modified with amino-modified silicones and the above-mentioned cyclic polymers. The same applies hereinafter in the description of the coating repair agent), higher fatty acids, higher alcohols, ester oils, interfaces. Activators, moisturizers, preservatives, plant seed extracts, fragrances and the like can be mentioned.

  As specific examples of silicones, higher fatty acids, higher alcohols, ester oils, surfactants, humectants and preservatives, various additives exemplified above as additives for hair internal repair agents can be used. Examples of the plant seed extract include sunflower seed extract.

  The film repair agent can be in the form of, for example, a cream, a lotion, or a gel, and water is the main dispersion medium. Note that some of the various components described above may be dissolved in water. Further, all of the dispersion medium may be water, and may contain an organic solvent such as a lower alcohol (ethanol, isopropanol, etc.). However, if the amount of the organic solvent in the dispersion medium is increased, the scalp and the like may be stimulated. Therefore, the content of the organic solvent in the dispersion medium is preferably, for example, 5% by mass or less.

  In addition, the film | membrane repair agent can use what differs in a component composition according to the property of the hair to process. For example, in the case of thin hair or hair having a normal thickness and relatively not damaged, for example, the above amino-modified silicone: 1 to 10% by mass, using water as a dispersion medium, A film repairing agent comprising 0.5 to 5% by mass of a cyclic polymer, 0.5 to 5% by mass of the above-described cationic surfactant, and 1 to 10% by mass of the above higher alcohol is used. It is preferable. In addition to these components, for example, various components exemplified above may be blended with the film repair agent as necessary.

  Further, for relatively hard hair, hair with a habit (so-called comb hair), wave hair treated with a permanent wave agent, etc., for example, the above amino-modified silicone: 1 to 10 mass using water as a dispersion medium %, The above wax esters: 1 to 5% by mass, the above cationic surfactant: 0.5 to 5% by mass, the above higher alcohols: 1 to 10% by mass, etc. It is preferable to use an agent. In addition to these components, for example, various components exemplified above may be blended with the film repair agent as necessary.

  The application amount of the film repair agent is not particularly limited. For example, an appropriate amount of the film repair agent is applied mainly in a place where the film is damaged and the texture (flexibility, gloss, etc.) is lost due to the presence of the film. do it.

  Hereinafter, the present invention will be described in detail based on examples.
